i thought that in Jessica Simpsons "With You", "the real me is a southern girl..." but i thought she said "to grill me is a southern girl". And my sister thought that "nothin but a tee shirt on" was "nothin but a t shidone" (whatever that means lol)

I read an article recently about "mondegreens," where the author starts by saying he was listening to Clay Aiken's song "I Survived You," and he could not understand why Iowans would write Clay off.
He thought the song said "When you wrote me off like Iowans do." That seemed strange. He could understand Iowans writing off a political candidate but not a wholesome down to earth kid like Clay.
Later he discovered the line is really "When you wrote me off like I was doomed."

I'm notoriously bad at just stringing together sounds and making up lines for songs I've heard. Some of my screwups that my friends and I have laughed about over the years:
"Voices Carry" by Til Tuesday: "Oh, Judge. Take it downtown. This is Carey."
